[quote]Add in the fact that heavier arrows have greater momentum which is more important once the arrow has hit hide, muscle and bone that can and will deflect it's energy easier with a lighter arrow.[quote]
Theory is great, but reality is better.
Gain in KE is the wrong word. YOU WILL GAIN PENETRATION!!!
This is reality - theory is proven in the math.
Straightarrow -you are not considering the amount of surface area on the projectile.
Reality is the WELL KNOWN fact that smaller diameter carbons penetrate farther than my fat alluminums. I have ridden both sides of this fence - I switched to carbons when the first came out. Back to alluminum because of the durability factor of the early carbons. After 10 years of that I'm back on carbons because of the REALITY of the physics involved.
A heavier arrow also is less affected by wind resistance, therefore downrange the lighter arrow is losing it's K.E. at a faster rate.
- A heavier arrow with THE SAME DIAMETER is less affected by the wind. If you really believe that a lighter arrow is lossing it's KE at a faster rate you need to study the charts a little bit more. FACT - a smaller diameter shaft is LESS affected by the wind = SURFACE AREA. The small difference in weight DOES NOT offset the larger surface area variable - which is what is considered when thinking about crosswinds!!!!
I know this has been beat to death so I will quit here - but you really should take a look at the math involved and then sink some carbons next to your fat alluminums out of the same setup.
YOU will have a REALITY CHECK.
